sorting and filtering

i'm tying to sort using location and filter using name. but unsure it what i have done on the server side is working. as nothing happens when i'm using the button and text field. i get all the projects, but its not sorting or filtering

const getAllProjects = async (req, res) => {
    const {
        _end,
        _order,
        _start,
        _sort,
        name_like = "",
    } = req.query;

    const query = {};

    if (name_like) {
        query.name = { $regex: name_like, $options: "i" };
    }

    try {
        const count = await Project.countDocuments({ query });
        const projects = await Project
            .find(query)
            .limit(_end)
            .skip(_start)
            .sort({ [_sort]: _order });

        res.header("x-total-count", count);
        res.header("Access-Control-Expose-Headers", "x-total-count");

        res.status(200).json(projects);
    } catch (error) {
        res.status(500).json({ message: error.message });
    }
};

const getAllProjects = async (req, res) => {
    const {
        _end,
        _order,
        _start,
        _sort,
        name_like = "",
    } = req.query;

    const query = {};

    if (name_like) {
        query.name = { $regex: name_like, $options: "i" };
    }

    try {
        const count = await Project.countDocuments({ query });
        const projects = await Project
            .find(query)
            .limit(_end)
            .skip(_start)
            .sort({ [_sort]: _order });

        res.header("x-total-count", count);
        res.header("Access-Control-Expose-Headers", "x-total-count");

        res.status(200).json(projects);
    } catch (error) {
        res.status(500).json({ message: error.message });
    }
};

Hi @nivored. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

---------------------- Based on the provided code, it seems like you have implemented server-side sorting and filtering for your projects. However, to help you further, I would need more information about how you are using refine to interact with this server-side implementation. Refine provides a way to handle sorting and filtering using the dataProvider. You can update the getList method in your dataProvider to handle the sorting and filtering parameters. Here's an example of how to handle sorting and filtering in the getList method:

getList: async ({ resource, pagination, sorters, filters }) => {
  const url = `${apiUrl}/${resource}`;

  const { current = 1, pageSize = 10 } = pagination ?? {};

  const query = {
    _start: (current - 1) * pageSize,
    _end: current * pageSize,
  };

  if (sorters && sorters.length > 0) {
    query._sort = sorters[0].field;
    query._order = sorters[0].order;
  }

  if (filters && filters.length > 0) {
    filters.forEach((filter) => {
      if (filter.field === "name" && filter.operator === "contain") {
        query.name_like = filter.value;
      }
    });
  }

  const { data, headers } = await axiosInstance.get(`${url}?${stringify(query)}`);

  const total = +headers["x-total-count"];

  return {
    data,
    total,
  };
},

getList: async ({ resource, pagination, sorters, filters }) => {
  const url = `${apiUrl}/${resource}`;

  const { current = 1, pageSize = 10 } = pagination ?? {};

  const query = {
    _start: (current - 1) * pageSize,
    _end: current * pageSize,
  };

  if (sorters && sorters.length > 0) {
    query._sort = sorters[0].field;
    query._order = sorters[0].order;
  }

  if (filters && filters.length > 0) {
    filters.forEach((filter) => {
      if (filter.field === "name" && filter.operator === "contain") {
        query.name_like = filter.value;
      }
    });
  }

  const { data, headers } = await axiosInstance.get(`${url}?${stringify(query)}`);

  const total = +headers["x-total-count"];

  return {
    data,
    total,
  };
},

This example assumes that you are using the sorters and filters parameters in your refine application. You can refer to the following documentation and tutorial sections for more information on how to implement sorting and filtering in refine: - Adding Sort and Filters (Ant Design) (https://refine.dev/docs/tutorial/adding-crud-pages/antd/adding-sort-and-filters) - Adding Sort and Filters (Headless) (https://refine.dev/docs/tutorial/adding-crud-pages/headless/adding-sort-and-filters)

If you still face issues, please provide more information about your refine implementation, specifically how you are using the dataProvider and handling user interactions for sorting and filtering. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this is the client side logic for that serverside logic

    const {
        tableQueryResult: { data, isLoading, isError },
        current,
        setCurrent,
        setPageSize,
        pageCount,
        sorter,
        setSorter,
        filters,
        setFilters,
    } = useTable();

  const allProjects = data?.data ?? [];

    const currentLocation = sorter.find((item) => item.field === 'location')?.order;
    const toggleSort = (field: string) => {
        setSorter([{ field, order: currentLocation === "asc" ? "desc" : "asc" }]);
    };

    const currentFilterValues = useMemo(() => {
        const logicalFilters = filters.flatMap((item) =>
            "field" in item ? item : [],
        );

        return {
            name:
                logicalFilters.find((item) => item.field === "name")?.value || "",
        };
    }, [filters]);

    const {
        tableQueryResult: { data, isLoading, isError },
        current,
        setCurrent,
        setPageSize,
        pageCount,
        sorter,
        setSorter,
        filters,
        setFilters,
    } = useTable();

  const allProjects = data?.data ?? [];

    const currentLocation = sorter.find((item) => item.field === 'location')?.order;
    const toggleSort = (field: string) => {
        setSorter([{ field, order: currentLocation === "asc" ? "desc" : "asc" }]);
    };

    const currentFilterValues = useMemo(() => {
        const logicalFilters = filters.flatMap((item) =>
            "field" in item ? item : [],
        );

        return {
            name:
                logicalFilters.find((item) => item.field === "name")?.value || "",
        };
    }, [filters]);

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the provided client-side logic, it seems like you are using the useTable hook to handle sorting and filtering. To ensure that the sorting and filtering are working correctly, you need to pass the resource parameter to the useTable hook. The resource parameter is the name of the resource that you want to get the data from (e.g., "projects"). It will be passed to the getList method in your dataProvider. Here's an example of how to use the useTable hook with the resource parameter:

const {
    tableQueryResult: { data, isLoading, isError },
    current,
    setCurrent,
    setPageSize,
    pageCount,
    sorter,
    setSorter,
    filters,
    setFilters,
} = useTable({
    resource: "projects",
});

const {
    tableQueryResult: { data, isLoading, isError },
    current,
    setCurrent,
    setPageSize,
    pageCount,
    sorter,
    setSorter,
    filters,
    setFilters,
} = useTable({
    resource: "projects",
});

Make sure that your dataProvider implementation is handling the resource parameter correctly, as shown in the previous answer. If you have followed these steps and still face issues, please provide more information about your refine implementation, specifically how you are using the dataProvider and handling user interactions for sorting and filtering. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
